Title: Production of hydrogen
Inventor: KRABETZ RICHARD
IPC: B01J23/86
Filed: 1964-12-04
Abstract: Hydrogen is produced by reaction of carbon monoxide or gases containing carbon monoxide with steam at below 250 DEG  C. in contact with catalysts prepared by coprecipitation of a sparingly water-soluble or insoluble compounds of, copper and aluminium together with chromium compounds and/or manganese compounds or by precipitation of compounds of copper and chromium and/or manganese on to an oxide or hydroxide of aluminium and subsequent reduction at below 250 DEG  C., and in which the weight ratio of copper to aluminium is from 1:1 to 20:1.  The gas to be converted may be obtained from the cracking o gaseous or liquid hydrocarbons and the conversion may be at 160-200 DEG  C. at atmospheric or super-atmospheric pressure, e.g. at 5-35 atmospheres. The catalysts may have weight ratio of copper to chromium and/or manganese from 100:0.5 to 100:24.  When the insoluble compounds are precipitated on the aluminium compound an aqueous suspension of aluminium hydroxide gel which has been freshly precipitated with ammonia may be used. Coprecipitation may be carried out by adding a solution of say the nitrates, sulphates or chlorides of copper and aluminium together with chromium and/or manganese to a strongly diluted solution of alkali metal hydroxide or carbonate or ammonia or ammonium carbonate at 15-95 DEG  C. or by precipitation at constant pH by adding the reactants uniformly to the reactor.  The precipitate is washed and dried at 105-200 DEG  C. and may be calcined say at 650 DEG  C.  The catalyst may be pelleted or extruded before or after calcination and subsequently reduced by heating to 130-200 DEG  C. in a gas containing carbon monoxide, e.g. the gas to be used in the conversion reaction.ALSO:Catalysts for the reaction of carbon monoxide or gases containing carbon monoxide with steam at below 250 DEG C are prepared by coprecipitation of a sparingly water-soluble or insoluble compounds of copper and aluminium together with chromium compounds and/or manganese compounds or by precipitation of compounds of copper and chromium and/or manganese onto an oxide or hydroxide of aluminium and subsequent reduction at below 250 DEG C and in which the weight ratio of copper to aluminium is from 1:1 to 20:1.

Abstract: 1334147 Steam drying of filter cake in rotary filter ENVIROTECH CORP 1 Nov 1971 [30 Oct 1970] 50687/71 Heading B1D Filter cake, formed on a rotary drum or discs 14 in passing through a bath of slurry while subject to an interior vacuum applied through receiver 22, is dried by applying superheated or saturated steam thereto in the space above the slurry, the steam being drawn the slurry, where they are subjected to internal tions (Fig. 3, not shown), wherein all the steam is condensed within the cake so that the condensation front just reaches the filter medium on the drum or discs where the cake is removed therefrom, are maintained by varying the vacuum applied through receiver 22 and/or the rotational speed of the drum or discs. As shown, the temperature of gas drawn through receiver 24, which applies vacuum to the drum or disc sectors above the slurry surface, is monitored at 72 and automatically controls the vacuum in receiver 22, by adjusting valve 66, and the rotary speed, by variable speed drive (Fig. 2, not shown). Thus a rise in temperature at 72 indicating that steam is penetrating the cake increases the vacuum and the speed, restoring the status quo by increasing the thickness of cake building up and reducing the time for which the cake is exposed to the steam. In addition the rate of steam supply may be varied by valve 28, controlled either by sensor 72 or by a temperature monitor 37 in the upper part of the housing 18. Steam temperatures, and flow rates and cake thicknesses are exemplified.
